4,4′-Dichlorobenzophenone – dependence of the intensities of representative reflections on temperature. The upper diagram shows the heating and cooling curves for the 111 reflection present in the higher-temperature C2/c phase and absent in the lower-temperature I2/c phase. The converse applies to the 031 reflection. Each pair of heating–cooling curves follows the pattern of Fig. 4, but the mean temperatures, which would be expected to approximate to T0 for the system, are displaced by about 8 K.
